Q. GaAs is used in fabricating Gunn diode. Gunn diode is:

  • (A) bulk device
  • (B) sliced device
  • (C) made of different type of semiconductor layers
  • (D) none of the mentioned
Explanation by: Admin
a gunn diode is a bulk device, that is, it does not contain any junction but it is a slice of n-type gaas. p- type gaas does not exhibit gunn effect. hence it is a reversible and can be operated in both directions.
